Scientists at the University of Guelph have developed a new material: a hydrogel-based slime that generates electricity when compressed. This discovery paves the way for applications in wearable electronics, interactive design, and smart materials within the fashion, product, and packaging design industries.

How does it work?
The slime utilises a phenomenon known as triboelectric charging, where mechanical energy is converted into electrical energy through contact and friction. When the material is pressed or stretched, the internal polymers generate an electrical charge. This principle is already used in sensors and self-powered devices, but the unique structure of this hydrogel slime makes it more flexible and better suited for various applications.

Applications in design and material innovation
For fashion designers, this material offers opportunities for interactive clothing and accessories. Think of gloves or shoes that generate energy through movement, or garments that can send signals to other devices without requiring a battery or external power source. This could contribute to more sustainable wearables and the reduction of e-waste.

For product designers and packaging developers, this material offers possibilities for self-sustaining packaging that can generate electrical signals, such as smart labels or anti-counterfeiting applications. The hydrogel could also be used in tactile interfaces for consumer electronics or interactive packaging.

Future outlook
Although the technology is still in the experimental phase, this gel could contribute to a new era of self-sustaining electronic systems. Designers across various disciplines can benefit from this innovation by exploring new ways to integrate energy generation into everyday products and materials.
